Presents the green gas farmers

In Mortagne sur Sèvre, located in the Vendée region, ten farmers have set up a short recycling circuit for agricultural waste from livestock farming and local food industries. Organic residues are processed in the AgriBioMéthane methanization plant, supplying green gas for the natural gas distribution network and fuel for vehicles. A great illustration of how agriculture and eco-mobility can work together to revive the circular energy economy.

The AgrioBioMéthane plant in Vendée contributes to the energy conversion of agricultural waste. ENGIE commits with ENGIE Harmony Project.

The Pioneers behind the Project

Behind this project, there are women and men working together to shape a better world for all of us. Their strength lies in the complementary nature of their expertise and their drive to lead a powerful collective effort that benefits all. These passionate people are the Imaginative Builders.

"One thing I immediately liked about this project was the fact that the biomethane produced is used locally. It’s also a team project that was started and led by an agricultural collective, a first in France!”

Alessandra Barba

"This project is a beautiful example of decentralized green energy production. I really want this kind of initiative to grow locally. It's a big opportunity for regions."

Grégoire Cestre

"I want this project to make everyone realize that there is more than fossil fuel. Today, waste can be a valuable resource too!"

Green Gas: One Energy, Multiple Uses

Green gas – or biomethane – is a source of clean energy that’s produced and consumed locally. It has a wide range of applications, including pairing with natural gas, as stored backup for intermittent renewable energies, or as BioGNV fuel. BioGNV significantly contributes to air quality improvement: its nitrogen oxide emissions are three times lower than those of traditional fuels (“Project Balance” study, April 2017). Biomethane is thus a key element in the energy transition.

ENGIE is a key player in biogas development in France, boasting more than 30 production sites (by the end of 2017).
